Application filed November 29, '1907: Serial No. 404,368.

' ingvlhad to the accompanying drawings.

y im rovement is particularly applicable to acety enegas generators wherein the water receptacle is superimposed upon the carbid casing and the water is permitted to gravi tat-eupon the carbidto deoompose'the latter;

' one ofthe disadvantages of such construcgenerator, the water 111 'sai -tion being that during the'o eration of the receptacle is maintained 'at a temperature above that of the surrounding atmosphere by; the heat liberat'ed from the decomposing 'carbid. .The

gas being generated at high temperature, carries considerable water as vapor, and it has been foundin practice that means for absorhing or filtering the Water from the gas .at

the generator 'fail to eliminate, moisture which is then vaporized, but which is subsequently precipitated when thegas iscooled in contact wit the gas conduit remote from the generator.

- Therefore, it isan objoct of my invention.

to combine with'an'acetylene gas generator,

' 'means local to the generatonwherei-n the gas will be-cooled to a temperature as low as it will attain at any time'before reaching-the burner, so'as to-separate fromthe gas and deposit in a predetermined location, from which it may be discharged at will, all of the mois- 4 ture which will" be preci itated .therefrom' ,prior to its combustion anc thus avoid cho k ing the gas'conduit with condensate deposited therein.

As hereinafter described, the means for effooting the condensation of the moisture from the gas, comprises a gas outlet pipe extending from the generator in a coilexposml to the atmosphere exterior-to said generator so that said coil is air cooled.

Ah gas has. been heretofore directed from an acetylene gas generator through a pipe submerged in water, either in the generapor or in a separate tank; I note that in accordance with the resent invention the condens ing pi e is neit er submerged in water nor inclose but is eX osed to the atmosphere so as to be aircoole the aforesaid construction or arrangement which is characteristic of the prior art fails of j) tLSSttgOWB It may be observed that its purpose, because, the temperature of the condensing-pipe surrounded by the water is raisedto such a degree that the entrained act-eristic' of my invention, the temperature ,of t e air cooled condensing pi e is substanconstant and such that t e moisture is continuously precipitated.

The acetylene gas generator hereinafter described, is so constructed that the water receptacle and the condensing coil may be permanentlylocat'ed in rigid relation with tial y each other in connection with an automobile,

and the carbid. casing be rigidly connected therewith and disconnected with respect thereto; such iionnection and disconnection being effected by rotation of a rod extending centrally in said water receptacle.

My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified.
